Re: Party crashers.
whatever the host did or did not do, the guest who took her along should have asked the host first, and she herself should have inquired from this other guest if her attending would be okay by the host.
two wrongs dont make a right , but lets not just focus on the wrongs of the host, or the guest who invited her (for staying). the fact that the invited guest and the tagalong did not have the courtesy of asking and assuming its okay is wrong as well.
